ABSTRACT:
A fouling monitor and method for sensing fouling in commercial waters and for differentiating between microbiological fouling and chemical fouling, which includes a dissolved oxygen probe disposed in a slip stream of water and means for providing an abundance of oxygen and nutrient to the microbial activity whereby a decrease in dissolved oxygen level is sensed due to the increased respiration of the microbes when microbiological fouling occurs. A polyester screen is mounted over the sensing end of the dissolved oxygen probe to promote microbiological fouling by providing a means for engaging the microbes and to enhance differentiation between the biological component and the non-viable/chemical component.
